The application provides an electronic equipment control method which can be used for controlling various electronic equipment. Electronic devices that may be used for control include, but are not limited to: mobile energy storage batteries, cell phones, computers, automobiles, and the like.

Specifically, the electronic equipment control method provided by the application is applied to a main control module in electronic equipment. The master control module may be any one or a combination of a plurality of micro control units (Microcontroller Unit, MCU), application processors (application processor, AP) and/or neural network processors (neural-network processing unit, NPU). When the electronic device is provided with a battery management system (Battery Management System, BMS), the main control module may be provided on the BMS of the electronic device.

Referring to fig. 1, an organization structure diagram of an internal module of an electronic device according to an embodiment of the present application includes a battery module and a plurality of working modules in addition to a main control module. The working module may include a power conversion module of the electronic device, a wireless network module of the electronic device, a storage module of the electronic device, or other types of modules, which are not limited herein. In this embodiment, the working module is a module that can implement a preset function and requires power consumption. The battery module is in communication connection with the main control module and receives control scheduling of the main control module. And each working module is also connected with the main control module in a communication way and receives the control scheduling of the main control module.

Referring to fig. 2, a flowchart of an electronic device control method according to an embodiment of the present application includes:

step S110, obtaining an initial electric quantity parameter value of the battery module.

In this embodiment of the present application, the initial power parameter value of the battery module is mainly used to describe the power value at the power-on time (may also be referred to as the initial time) of the device. It should be noted that the battery module always has a minimum electric power value during discharging or charging. The battery module does not release the electric quantity to 0 when discharging, and the discharging is stopped after the electric quantity is released to the lowest electric quantity value. The initial power parameter value of the battery module may be a remaining power corresponding to the device power-on time, or may be a state of charge SOC (State of Charge) of the device at the device power-on time, that is, a ratio between the remaining power and a full power of the battery module. For example, in a scenario of charging the energy storage power supply with the mains supply, the initial electric quantity parameter value may be a state of charge displayed by the energy storage power supply when the energy storage power supply is connected to the mains supply for charging. Powering up an electronic device generally refers to the device being in a power-on state, when the electronic device may be in an operating state or a sleep state.

And step 120, in each preset period, acquiring the accumulated electric quantity parameter value independently calculated by each working module through communication.

In the embodiment of the application, each working module independently calculates a corresponding module electric quantity parameter value. The accumulated electrical quantity parameter value is configured to characterize the total electrical quantity of the working module after power-up, i.e. accumulated in or out of the working module from an initial moment. The parameter value of the accumulated electric quantity can be the accumulated electric quantity calculated by the working module in an ampere-hour integral mode directly, or can be the ratio of the accumulated electric quantity to the electric quantity of the battery module under the full electric quantity.

The time length of the preset period can be set according to needs, for example, according to the sampling period of each working module. The preset period may be greater than or equal to the sampling period of each working module, and may be typically set to a millisecond level.

And in each preset period, the main control module establishes communication with each working module, and then obtains the accumulated electric quantity parameter value obtained by independent calculation of each working module. Because the work module can monitor the state of the work module in real time, the work module is not interfered by other factors, such as data loss caused by communication abnormality, and the accuracy of the accumulated electric quantity parameter value is not affected. Therefore, as long as the main control module can normally establish communication with the working module, the accurate accumulated electric quantity parameter value obtained by the working module in the accumulated metering period is obtained. The main control module cannot obtain accurate electric quantity parameter values due to communication abnormality in the middle, so that the method has stronger timeliness and data accuracy.

In the related technology, the electronic device obtains the instantaneous current parameter values on each working module in real time through the main control module, so as to calculate the residual electric quantity or the charge state based on the instantaneous current parameter values. Once communication abnormality exists between the main control module and the corresponding working module, instantaneous current parameters of abnormal devices cannot be obtained, so that the residual electric quantity or the electric charge parameters calculated by the main control module have larger deviation from actual values, and the residual electric quantity or the electric charge parameters cannot be automatically calibrated after communication is recovered. In this embodiment, the accumulated power parameter value independently calculated by each working module is obtained each time, and even if the communication is abnormal in a certain period of time, the main control module has a certain calculation deviation, but after the communication is restored, the actual power value can be restored, so that the reliability and accuracy of the data are improved.

Step S130, obtaining a first charge state of the device according to the initial electric quantity parameter value and each accumulated electric quantity parameter value.

In this embodiment of the present application, after obtaining an initial electric quantity parameter value of a battery module and an accumulated electric quantity parameter value of each preset period of each working module, a main control module combines the initial electric quantity parameter value and the accumulated electric quantity parameter value to obtain a first state of charge of the device. The accumulated electric quantity parameter value of each preset period independently calculated by the working module has stronger timeliness, so that the electric quantity value of the working module in each preset period can be reflected more timely and accurately, and the first state of charge of the electronic equipment obtained on the basis also has stronger timeliness, so that the state of charge of the electronic equipment in each preset period can be reflected more timely and accurately.

And step 140, determining that the communication connection between at least one working module and the main control module is abnormal when the absolute value of the difference value between the first charge state acquired in the current period and the first charge state acquired in the previous period is larger than a first preset threshold value.

It will be appreciated that the first state of charge will not typically be abrupt under normal operating conditions of the device. For example, when the device is stably loaded, the power consumed or transferred by each working module in each preset period is stable, so that the absolute value of the difference between the first states of charge obtained in two adjacent periods satisfies a stable relationship, and the stable relationship can be reflected by a first preset threshold value, so that when the absolute value of the difference is smaller than the first preset threshold value, the difference can be regarded as smooth change, rather than abrupt change. When the load of the electronic equipment is suddenly increased or the power supply is suddenly increased, the current of the electronic equipment is not suddenly changed, but gradually increased from small to large through strategies such as slow start and the like. And the preset period is of the order of milliseconds, so that it is also ensured that the resulting first state of charge does not mutate. The first state of charge is also a smoothly varying process, except that the slope of the change is steeper relative to light or no load, but no abrupt change occurs. When a certain working module is switched into a standby state or a non-working state from the working state, the communication between the working module and the main control module is still in a normal communication state, so that the working module still reports the accumulated electric quantity parameter value to the main control module, and abrupt change does not occur.

If the first state of charge is suddenly changed, the communication connection between the main control module and part of the working modules is abnormal, so that the main control module cannot receive the accumulated electric quantity parameter value of the part of the working modules. Since the integrated electric quantity parameter value is a value integrated from the initial time, the integrated electric quantity parameter value is a much larger value with respect to the electric quantity variation amount in each preset period, so that a larger deviation occurs in the calculation of the first state of charge. Therefore, a first preset threshold may be preset for the absolute value of the difference between the first state of charge acquired in the current cycle and the first state of charge acquired in the previous cycle. If the absolute value of the difference value is larger than a first preset threshold value, the first charge state obtained in the current period is suddenly changed, and further, the communication connection between at least one working module and the main control module is determined to be abnormal.

Wherein the first preset threshold should be set reasonably by a person skilled in the art, and the setting of the first preset threshold must be larger than the change value of the first state of charge that changes smoothly. For example, if the current load power of the electronic device does not change, and the work of each work module and the communication between each work module are also normal, the change value of the first charge state of the electronic device in each preset period is 0.1%, and the first preset threshold value can be set to be 0.3% or 0.5%, so that the situation of abnormal communication can be accurately judged, and the situation of certain fluctuation of the first charge state caused by sudden change of the load of the electronic device can be satisfied. The first preset threshold may be a fixed value, or may be set according to an operation state of the electronic device. For example, the main control module can determine the electricity consumption condition of each working module in a normal state in a preset period according to the current charge and discharge state, the power supply capacity of the power supply or the required power of the load, and the like, and determine a corresponding first preset threshold according to the electricity consumption condition. It is understood that the above setting of the first preset threshold is only used as an example and is not limited to the protection scope of the present application.

In an embodiment, after obtaining the first state of charge of the electronic device according to the initial power parameter value and each accumulated power parameter value, the method further includes:

and when the absolute value of the difference value between the first charge state acquired in the current period and the first charge state acquired in the previous period is smaller than or equal to a first preset threshold value, determining that the communication connection between each working module and the main control module is normal.

In this embodiment, as described above, the first state of charge of the electronic device should be smoothly changed under normal operation. In normal conditions, the absolute value of the difference between the first states of charge in each two adjacent cycles is always less than or equal to the first preset threshold value described above, for example 0.3% as described above.

In some embodiments, when the master control module determines that the communication connection between itself and each working module is normal, the master control module may consider that the current accumulated electric quantity value of each working module acquired by itself is accurate data, and the first state of charge calculated according to the data is also trusted. The main control module determines the first charge state acquired in the current period as the display charge state of the current period and displays the display charge state.

In this embodiment, when the absolute value of the difference value between the first states of charge acquired in two adjacent periods is smaller than or equal to the first preset threshold, the master control module determines that the communication connection between each working module and the master control module is normal, and based on the absolute value, the first state of charge calculated in the current period is used as the display state of charge, so as to accurately display the electric quantity of the electronic device in the current period.

The first state of charge of the electronic equipment has stronger timeliness, so that the state of charge of the electronic equipment in each preset period can be reflected more timely and accurately. Therefore, based on the first state of charge, the main control module can more timely and accurately detect that the communication connection between the working module and the main control module is abnormal, so that the electronic equipment can more timely and accurately respond to the situation that the communication connection between the working module and the main control module is abnormal.

In one embodiment, the accumulated electric quantity parameter values refer to the accumulated state of charge, i.e. the ratio between the accumulated electric quantity of each working module and the full electric quantity of the battery module, i.e. the state of charge SOC _n . At this time, the main control module obtains the state of charge SOC output by each working module _n . Each working module calculates the respective module electric quantity parameter value according to the following formula:

SOC _n ＝F _n /F*100％

wherein F is _n Represents the accumulated electric quantity of the nth working module, t represents the current moment, I _n Representing the current value obtained by monitoring the n-th working module in real time in the time period of 0-t (the time period of 0-t can comprise one or more preset periods, and the moment of 0 can represent the power-on moment of equipment), and the SOC _n Representing the state of charge of the nth operating module, and F represents the full charge of the battery module of the electronic device. It should be noted that the current I _n Is a parameter having a vector direction so that it can be determined whether the current operating module is charging the battery module or is consuming the power of the battery module according to its current direction. When the battery module is charged by an external power supply, a current I _n The direction of (2) is negative and the opposite direction is positive.

Therefore, the initial electric quantity parameter value of the battery module obtained by the main control module is also the state of charge (SOC) of the battery module _past . The state of charge SOC _past Representing the past remaining state of charge of the electronic device, namely the remaining state of charge of the electronic device at the time of power-up. The main control module is used for controlling the SOC according to the state of charge _past And state of charge SOC output by each work module _n Calculating a first state of charge, SOC, of the device according to the formula _A ：

Representing the sum of the states of charge of the working modules output to the master control module by integrating the initial state of charge SOC _past Subtracting the sum of the charge states obtained in each preset period to obtain the current first charge state SOC of the electronic equipment _A 。

In another embodiment, each working module can also be directly connected with each otherCalculated accumulated electric quantity F _n The parameter value is transmitted to a main control module as an accumulated electric quantity parameter value, and at the moment, the main control module needs to sum the accumulated electric quantity of each working module according to the requirement to obtain the total accumulated electric quantity F of each working module _A The following formula:

in the process of obtaining the total accumulated electric quantity F of each working module _A Then, if the initial electric quantity parameter value obtained by the main control module is the initial residual electric quantity F ₀ Then the first state of charge SOC is calculated by _A ：

In an embodiment, after determining that there is an abnormality in the communication connection between the at least one working module and the main control module, the method further includes:

and detecting the working module which does not send the parameter value of the accumulated electric quantity, and determining the working module which does not send the parameter value of the accumulated electric quantity as a communication abnormal module.

In this embodiment, after determining that a communication abnormality occurs between the working module and the main control module, the main control module may track the module that has the communication abnormality, and determine the module that has no communication abnormality by detecting the working module that has not sent the parameter value of the accumulated electric quantity. Because under the normal communication condition, the working module with normal communication can send the self accumulated electric quantity parameter to the main control module at certain intervals, even if the working module does not work in the current period, the last calculated accumulated electric quantity parameter can be continuously sent to the main control module periodically, for example, the inversion module needs to perform inversion work in the first period, but in the next period, inversion is not needed, but as long as the communication of the inversion module is normal, the last calculated accumulated electric quantity parameter in the first period can be still sent to the main control module in each period. When the communication of the working module is abnormal, namely the working module does not send the accumulated electric quantity parameter to the main control module, and the main control module determines the working module which does not receive the accumulated electric quantity parameter as an abnormal module through checking.

In some embodiments, when the working module sends the self accumulated electric quantity parameter to the main control module, the working module may be sent in a signal form carrying the accumulated electric quantity parameter. Therefore, when the working module sends the signal, the number pointing to the working module is added, for example, the number of the inversion module is 01, the number of the heat dissipation module is 02, when the main control module receives the signal carrying the number 01, the inversion module is considered to have no communication fault, and when the main control module does not receive the signal carrying the number 02, the heat dissipation module is considered to be a communication abnormal module. It is understood that the mode of the master control module for detecting the working module that does not send the parameter value of the accumulated electric quantity may be other communication judging modes, and is not limited to the example of the above embodiment, and a person skilled in the art may set the working module appropriately according to the actual requirement, which is not described herein.

In an embodiment, after determining that there is an abnormality in the communication connection between the at least one working module and the main control module, the electronic device control method provided in the present application further includes: and generating prompt information, wherein the prompt information is configured to prompt that the communication connection is abnormal.

In this embodiment, after determining that there is an abnormality in the communication connection between at least one working module and the main control module, in order to remind a host computer of the electronic device or a user of the electronic device, the main control module generates a prompt message for prompting that there is an abnormality in the communication connection. If the main control module is used for reminding the upper computer, the main control module can generate a contracted error code as prompt information according to the contract with the upper computer, so that the upper computer is reminded of abnormal communication connection. If so, the main control module can generate text or voice as prompt information to remind the user of abnormal communication connection. The prompt information can also be embodied in the forms of light, vibration and the like, and the specific expression form of the prompt information is not limited in the embodiment of the application.

In one embodiment, after determining that the working module that does not send the accumulated electricity parameter value is the communication anomaly module, the method further includes:

and taking the accumulated electric quantity parameter value which is transmitted by the communication abnormal module last time as the accumulated electric quantity parameter value which corresponds to the communication abnormal module and is acquired in the current period.

And updating the first charge state of the current period according to the initial electric quantity value and each accumulated electric quantity parameter value acquired in the current period.

In this embodiment, after determining that the communication abnormal module occurs in the electronic device, in order not to seriously affect the calculation of the first state of charge of the entire electronic device, after determining that the communication abnormal module is determined, the main control module may further use the last transmitted accumulated electric quantity parameter of the communication abnormal module as the accumulated electric quantity parameter value corresponding to the communication abnormal module obtained in the current period even if the accumulated electric quantity parameter of the communication abnormal module is not temporarily obtained due to the communication fault. For example, after determining that the heat dissipation module is a communication abnormal module in the current period, the main control module is about to acquire the accumulated electric quantity parameter of the heat dissipation module in the nearest period as the accumulated electric quantity parameter of the heat dissipation module in the current period.

Thus, the main control module can have the accumulated electric quantity parameters of all the working modules (including the communication abnormal module) in the electronic equipment, and calculate the new first state of charge according to the initial electric quantity value and the accumulated electric quantity parameters of all the working modules (including the communication abnormal module) so as to update the first state of charge in the current period.

In this embodiment, the accumulated electric quantity parameter of the communication abnormal module sent last time is replaced by the accumulated electric quantity parameter of the communication abnormal module in the current period, so that the gap of data loss caused by communication abnormality is filled, and further the problem of larger error of the main control module when calculating the first charge state of the electronic device is avoided.

In an embodiment, displaying the first state of charge acquired in the current period includes:

and acquiring the display charge state of the previous period.

And when the absolute value of the difference value between the first charge state acquired in the current period and the display charge state of the previous period is smaller than or equal to a second preset threshold value, determining the first charge state acquired in the current period as the display charge state of the current period and displaying the display charge state.

The second preset threshold is set for giving the user a better use experience, so that the display charge state is stably changed in a certain linear relation rather than abrupt change when displayed. For example, the second preset threshold may be set to 1%, that is, the absolute value of the difference between the display states of charge for display in two adjacent periods before and after the electronic device is charged or discharged is only allowed to have an error of 1%.

As mentioned previously, the first state of charge is merely an accumulated charge parameter value that can be obtained for each of the operating modules. When the communication abnormality exists, the working module which needs to acquire the communication abnormality acquires the accumulated electric quantity parameter values recently and sequentially, and then the first state of charge is corrected and displayed. Of course, other correction methods may be used to correct the final state of charge to have higher accuracy. Therefore, the first charge state obtained directly is compared with the display charge state of the previous period, whether an abnormality occurs can be also determined, and if the absolute value of the difference value between the first charge state and the display charge state is smaller than the second preset threshold value, the communication can be determined to be normal, so that the first charge state can be displayed as the display charge state without being corrected directly.

In an embodiment, when the absolute value of the difference between the first state of charge acquired in the current period and the display state of charge of the previous period is greater than a second preset threshold, the display state of charge of the current period is determined and displayed according to the display state of charge of the previous period and a preset adjustment value.

Specifically, after the first state of charge of the current period is calculated, the main control module temporarily stores the first state of charge in a memory for calculation and comparison of the next period. And determining and displaying the display charge state of the current period according to the preset regulating value and the display charge state of the previous period.

In an embodiment, the electronic device control method provided by the present application further includes: and respectively acquiring sampling current values of the working modules in each preset period. And calculating a second charge state of the equipment according to each sampling current value and the initial electric quantity parameter value. And when the absolute value of the difference value between the first charge state and the second charge state is smaller than a preset threshold value, determining and displaying the charge state of the device according to the first charge state and the second charge state.

In this embodiment, the sampling current value of the working module refers to a current value obtained by sampling its own current by the working module. And in each preset period, the main control module establishes communication with each working module, and then obtains the sampling current value of each working module. And then the main control module can calculate the accumulated electric quantity parameter value of each working module according to each sampling current value, and then calculate the second state of charge of the equipment by combining the initial electric quantity parameter value of the battery module.

It should be noted that, the value of the accumulated electric quantity parameter of the working module for calculating the first state of charge is calculated by each working module independently. The accumulated electric quantity parameter value of the working module for calculating the second state of charge is calculated by the main control module according to the sampling current value of each working module.

If the absolute value of the difference between the first state of charge and the second state of charge is smaller than the preset threshold, both of the absolute value and the second state of charge can be used for reflecting the state of charge at the current moment of the device, so that in order to improve the rationality of the state of charge displayed by the device, the state of charge which should be displayed at the current moment of the device (namely the displayed state of charge of the current period) is determined by integrating the first state of charge and the second state of charge. For example, the first state of charge and the second state of charge are weighted and averaged to obtain the amount of power to be displayed.

In one embodiment, the master control module calculates the second state of charge of the device according to the following formula:

wherein F is _B Sampling current value I 'representing the main control module according to n working modules' _n The calculated total electric quantity values of the n working modules, namely, the main control module firstly obtains the electric current values of all the working modules, and the total electric quantity values of the n working modules are obtained through ampere-hour integration according to the sum of the electric current values of all the working modules. t represents the current time, I' _n Representing the sampling current value of the nth working module in the period of 0-t (the period of 0-t can comprise one or more preset periods, and the moment of 0 can represent the power-on moment of the equipment), and SOC _B Represents a second state of charge, F ₀ Representing the charge capacity value corresponding to the initial charge parameter value of the battery module, and F represents the total charge capacity value of the device.
